i To aZZfwtom t may concern:

Be it known that I, EDWARD S. LIDsToNE, a citizen of the UnitedStates, and a 'resident of Providence, in the county of Providence and State of Rhode Island, have invented a new and Improved Pumping Mechanism, of which the following is a full, clear, and exact description. y Y

This invention relates to pumping mechanisms. y

An object oi' the invention is to provide a pulnping mechanism `capable of being quickly assembled and disassembled and packed in a small space when disassembled,

which virtue is particularly advantageous when the pump 1s to be used 1n connectlon wlth automobiles.

Another object is the provision of a plu` rality of cylinders with the mechanism `so that the pumping action is rapid, the cylinders being so mounted as to assume closely related positions when the unit is disassembled. y

y The invention further resides in the construction and arrangement of the parts `as described more in detail in the following specification and claims.`

The invention in general comprises a frame made in-a plurality of sections, `one section being so constructed that-it can slide telescopically into andwith relation to another section. Each section is adapted to support a pumping device, such as a cylinder. Connecting means are provided to connect the sections and hold them when so connected in position suitable for the operation ot' the cylinders to pump. This connecting means hasassociated therewith an oscillating member which is adapted to be connected to the cylinder piston and operate the same. i The cylinders are adjustably pivoted on the sections and by reason of this adjustment can be disposed in any suitable relation during` pumping and can be disposed closely adjacent to each other when onesection istelescoped within another. 1, l -By reason of the above-mentioned general features there has been provided a pumping unit which is simple in construction, capable of ready assembly, and which occuples comparatively y small space when disassembled.

The invention is illustrated in the drawing, of which- Figure 1 represents a side elevation of the mechanism;

`F ig. 2 represents a plan view of the mechamsm;

Fig. 3 represents an elevation partly section showing the cylinders in the position they occupy when the mechanism is disassembled;

Fig. 4 is a partial profile View;

gig. 5 is a detail view of a cylinder pivot; an

Fig. 6 is another view of this pivot.

As illustrated in the drawing, the pumping mechanism comprises a plurality of sections, such as 1 and 2, each of which has base portions 3 and 4 and vertically extending portions 5 and 6. One of the sections, such as 2, is also provided with horizontally extending wing portions 7 and 8 by means of which the mechanism may be mounted on a support or attached to some rigid structure, such as the running board of an automobile. The base portions 3 of the section 1 are spaced apart such a distance as will ermit them to contact along their edges with tle inner faces of the base portions of section 2. WVhen the sections are in the position shown in Fig. 1, a connecting link or bar 9 is adapt- 'ed to extend through suitable apertures in the base portions of each section to hold them in this fixed position. lVhen this link or bar 9 is withdrawn, the section 1 is adapted to slide within the `section 2 and when thus disposed the apparatus takes up slightly more than half the space occupied by the apparatus when in operating position. On the vertical portions 5 and 6 of the sections,

` pumping devices, such as c linders 10 and 1l, are mounted. These cy inders are provided with heads 12 and 13 between which bolts 14 extend to hold the heads 12 and 13 on to the body portion of the cylinders. Suitable pistons 15 are provided and can connect with the actuating member or bar 16`by means of connecting rods 17 and 18. This actuating member 16 may be jointed, as shown at 19, in any suitable manner, so that when the mechanism is disassembled the handle portion can be packed away in a small compass. This actuating member or bar IG is pivotally mounted on the connecting bar 9.

lThe cylinders 10 and 11 are pivotally mountedonjtheupper ends of the vertical portions 5 and 6 of the sections 1 and 2. This pivotal mounting comprises, as shown in Figs. 5 and 6, anA eye holt 2O having a shank 21 which is threaded on its outer end and extends through an aperture 22` in the vertical portions 5 and 6. A Winged nut 23 is threaded .on to the outer end of the shank 21 to tighten the same. v Hthin the aperture 22 is a collar 24: loosely surrounding the shank 2l and provided at its outer end with a curved janT 25 adapted Ato engage with one face Vof the bolt 14. It is apparent Jfrom an inspection of Figs. 5 and 6 that When the Winged nut 23 is moved to pull the eye bolt 20 into the aperture 22, the jaw 25 tightly ygrips the bolt lat soy that the point along bolt ltat which the cylinder is pivoted is liXed, although this construction permits the oscillation of the cylinder about this point.

The cylinders at one end are provided With outlet cocks 26 to Which any suitable connection may be made.

When it isrdesired to disassemble the device from the condition shown in Fig. l to that condition in Which it will occupy a minimum amount of space, suoli as shown in Fig. V3,v the actuating member 1G is disconneeted from the connecting rods 17 and 18 and from the connecting bar 9, after Which it is taken apart at the joint 19. The pistons lare then moved to theinn-ermost portion of the cylinder. The Winged nuts 23 are loosened and the cylinders moved into positions parallel to each other, as shown in Fig.` 3. kThe sect-ion l is then moved inwardly Within theA section 2 until the cylinders lie Aclosely adjacent each other; Whereupon it is seen that thejamount of space oc'- cupied by the entire unit is very considerably less than when it is in operating condition.
